AUTOMOBILE CHASSIS-GREASING APPARATUS.

Application filed April 4,

The present invention relates to an apparatus-for automatically greasing the various parts of an automobile chassis and has for its principal object to provide a structure which is in operation when the automobile is'moving to force the grease to the various chassis parts at a predetermined rate, in direct ratio to the speed of the automobile.

Another very important object of the invention resides in the provision of a greasing apparatus of this nature which is operated from the speedometer table.

Another very important object of the invention lies in the provision of a greasing apparatus of this nature which is comparatively simple in its construction, exceedingly compact and convenient, easy to manipulate. refill, and regulate, thoroughly eflieient and reliable in operation, comparatively inexpensive to manufacture, strong and durable, not likely to easil become out of order, and otherwise well a apted to the purpose for which it is designed.

With the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of arts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a side elevation of the apparatus embodying the features of my invention.

Figure 2 is a horizontal transverse section therethrough taken substantially on the line 2-2 of Figure 1.

Figure 3 is a vertical section taken through the device, substantially on the line 3-3 of Figure 2,

Figure 4 is a transverse horizontal section taken substantially on the line 4-4 of Figure 3,

Figure 5 is a similar section taken on the line 5-5 of Figure 3.

Figure 6 is a perspective view of the washers.

Figure 7 is a perspective view of the lock for holding the casing closed.

Referring to the drawings in detail, it Wlll be seen that the casing comprises an upper portion 5 and a lower portion The upper portion of the casing 5 functions as a top, while the lower portion of the casing functions as a holder for the greased cylinders.

1927. Serial No. 180,846.

These sections 5 and 6 are hingedly connected together as at 7. The section 6 has attached thereto a pair of suitable brackets 8, in order that it may be conveniently mounted on the automobile.

The numeral 9 denotes a cylinder block. having a bottom head 10 and a top head 11. A plurality of different sized cylinders 12 are formed in the block 9 and in the head 11. A packing plate 13 is disposed between the cylinder block 9 and the bottom head 10. Dowel pins 14 connect the block 9 and the head 10. The head 10 is formed with passages 15, communicating with the bottom ends of the cylinders 12 through openings in the packings 13. A washer 16 is disposed in the bottom of each cylinder 12 and is trans verseiy split as at 17 so that the portions between the splits will extend downwardly when the grease is forced therethrough in a manner which will be described later. These parts prevent the grease from flowing from the cylinders except upon pressure. Internally threaded recesses 18 are formed in the passages 15 at their lower ends to receive coupling nipples 19 to which may be attached flexible or other conduits 20 leading to the portion of the chassis to be lubricated,

such as the spring 21, indicated in Figure 3.

by way of example. It will be understood that there will be one cylinder 12 for every important point of the chassis needing lubrication or as many. as may be desired, this may be a matter of preference and controlled, of course, somewhat in accordance with the type of automobile upon which the device is to be used.

Plunger rods 22 are slidable through the head 11 into the cylinder 12 and have mounted on their inner ends plungers 24 for rectilinear movement in the cylinders. A carrier plate 25 is mounted for vertical movement in the casing portion 5, and the upper ends'of the rods 22 are fixed thereto in any suitable manner. Rods 26 are mounted in two opposed corners of the casing section 5 and extend through openings in the carrier late 25 and function as guides therefor. A bracket 28 rises from a portion of the head 11 in an ofiset portion 5' of the casing section 5 and has journaled therein a worm 29, which =s operable by a flexible cable structure 30 connected with a transmission structure 31, with the flexible cable structure 32 of a speedometer mechanism 33, so as to rotate through suitable gearing 34 at a predetermined ratio with respect to said speedometer cable. Brackets 35 ride from the carrier plate 25 and have journaled therein a shaft 36, which has a worm gear 37 in mesh with the worm 29 and is also provided with a worm 38 in mesh with a relatively large worm gear 39, fixed on a shaft 40 which extends down through a central opening in the carrier plate 25 and into a central bore 41, in the block 9. A retainer plate 42 is fixed in the casing section 5 below the carrier plate 25 and above the head 11. This head 11 is also fixed to the bottom end of the section 5. A hinged split nut structure denoted generally by the letter N is disposed between the head 11 and the retainer plate 42, and comprises a pair of sections 43 hinged together as at 44, and havin curved ends 45. A member 46 has pin and slot connections 47 with the ends 45, and is swingable by means of a lever 48 pivoted as at 49 between the retainer plate 42 and the head 11. This lever extends through a slot 50 in the caslng section 9 so as to be accessible from the exterior thereof.

Dowel pins 51 are fixed either in the head 11 or the block 9 for holding the head and block in proper relation to each other with their cylinders 12 in registry as is shown to advantage in Figure 3. The rods 26 extend through the top of the casin section 5 and have attached thereto a ban le 52, for carrying the apparatus from place to place, when this is necessary. A lug 53 projects from the head 11 and a similar lug 54 projects from the head 10. A locking mechanism of suitable formation is engaged with these lugs and in the present instance comprises the fork 55 engaged with the lug 54. A hook rod 56 extends from the fork 55. A link 57 is engaged with the lug 53 and has a lever 58 rockable thereon. Thus, the hooked end of the rod 56 may be engaged with the end of the lever and the lever swung to the position shown in Figures 1 and 7, for locking the sections 5 and 6 in the positions shown in Figures 1 and 3, with the parts assembled.

It is thought that the details of construction should now be suificientl clear to thoroughly understand the ut-i it operation, and advantages of the apparatus. To fill the apparatus, the lock structure is released b swin ing upwardly on the lever 58 so that t e hoo rod 56 may be disengpged there from. Then the section 5 wit the parts mounted therein may be swung. open after the handle 52 has been lifted up, causing the rods 26 to be lifted up with the carrier plate 25, to pull the plunger 24 out of the cylin-- ders 12 in the block 9. Obviously, the cylinders 12 may then be filled with grease. The lock nut N which was previously released 18 then engaged with the lower end of the worm or screw 40 and the'section v5 is swung screw above the p back in place and looked, as will be quite a parent, and thus will be seen that the p unger 24 is at the to of the cylinder 12. Now, when the automo ile starts in motion, of course the worm 29 is rotated and transmits this rotary movement through worm gear 37, shaft 36, and worm 38-to worm ear 39, thereby rotating the screw 40 w ich through the nut N pushes the plate 25 downwardly, at the same time causing the plunger 24 to move downwardly in the c linder and force the grease throu h the ottom end thereof as previously in icated.

The present embodiment of the invention has been disclosed in detail merely by way of example, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above descri tion. It will be apparent that numerous c anges in the details of construction, and in the combination andarrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed-or sacrificing any of its advantages.
